What is Melanotan II?

Melanotan II (MT-II — synthetic alpha-MSH analog) is a 7-amino acid cyclic lactam peptide. Synthetic alpha-MSH analog activating MC1R (melanogenesis — skin pigmentation, UV photoprotection) and MC4R (appetite suppression, energy balance, sexual function). Broader melanocortin receptor profile than selective MC1R agonists, with both peripheral pigmentation and central appetite/sexual function effects.

Research Applications

MC1R Melanogenesis

Eumelanin production, UV photoprotection, pigmentation biology

MC4R Central Effects

Hypothalamic appetite suppression, energy balance via MC4R

Sexual Function

Central MC4R-mediated sexual arousal and function pathways

Melanocortin Selectivity

MC1R + MC4R dual vs selective receptor comparison

Skin Biology

Pigmentation research, melanocyte activation, photoprotection
